2 shops in 1 domain and

I use joomlshopping for a pony society website.
Members can buy pony stuff.
In the topnavigation I have a category 'For sale'
In the subnavigation 'for sale/pony articles' (this is where I'm using it for).
But there is also an subnavigation for sale/horses. I would like to use joomshopping as well. But for this shop I need different rules. This because you can not put horses in your basket:).
Is it possible to show different categories/products in each subnavigation (horses in the for sale horses and products in the for sale products)?
I saw that its possible to select a different category in the mainmenu/main menu type. But only 1 category. Or is it possible to have 2 shops in 1 website without going to another domain?

And is it possible to switch of the buy button and the price button?
Thank you for your help!
